FEED-COCK.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Original application filed Ju1y 30, 1910, Serial No. 574,744. Dividedand this application filed October 20, 1911. Serial No. 655,815.

To all whom it may concern:

Be it known that I, TVELLINGTON P. IN- TER, a citizen of the UnitedStates, and a resident of Toledo, in the county of Lucas and State ofOhio, have invented a certain new and useful Feed-Cock; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying .drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to feed or drip cocks for use in any connectionwhere a regular and uniform dripping or feeding of a liquid is desired.In the use of feeds of this character considerable difficulty isexperienced by reason of an improper feeding of the liquid under varyingconditions of use. This is particularly noticeable in carbureter feedsas an improper feeding of the gasolene thereto causes numerous troubles,such as a flooding too weak a mixture, irregular explosions, etc.

The object of my invention is the provision of a liquid feeding means ofthis character, which is simple and economical in its construction andadapted to obviate the objections incident to the use of the meansheretofore employed for such purpose, thus enhancing the practicabilityand commercial value thereof.

Further objects and advantages of my invention will be apparent from thefollowing description.

The invention is fully described in the following specification, andwhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, which is a central longitudinal section of the invention inconnection with a source of liquid supply.

This application is a division of an application filed by me on July 30,1910, Ser. No. 57 1,74 1, and which has matured into Patent No.1,009,205, dated Nov. 21, 1911.v

Referring to the drawings, 1 designates a drip or feed cock embodyingthe features of my invention, which may be attached to a float-chamber2, or to any other suitable source of liquid supply. The cock 1 isprovided with a throat portion 3, which is in communication with thesource of liquid supply, and may be termed the supply passage of thecock, and with the throat portion 4, which is in valve-control1edcommunication with the passage 3 and may be termed the drip-passage ofthe cock. The drip-passage 1 is open to the atmosphere at both ends, orat opposite sides of its point of communication with the passage 3, andis shown in the present instance as having its upper end portionextending at an incline past the lower or outlet end portion of thepassage 3, whereby liquid may have a gravity or pressure flow throughthe latter passage. The flow of liquid from one to the other of saidpassages is controlled by a needle-valve 5, which is threaded, in thepresent instance, through a side of the cock and extends across thepassage 3 with its valve end working in a communicating opening 6between the two passages to close or open it to a predetermined extent.Vhile the opening 6 may be placed at any convenient point relative tothe passage 3, it is important that it communicate with the passage 4through a side wall thereof intermediate its ends. The stem of the valve5 carries a finger 7 which coacts with a pivoted stop 8 at apredetermined point in each revolution thereof to stop the rotation ofthe valve. The valve is adapted upon each complete turn to permit anemission of a predetermined number of drops per minute from the cock.

It is found in practice that the opening of the passage 4 to theatmosphere above its point of communication with the opening 6 not onlyrenders the cock more efficient and regular in its dropping or uniformfeeding action than cocks heretofore employed but also that theefficiency is enhanced by prolonging the passage 41 for a considerabledis tance above the opening 6.

The float chamber 2, which in reality forms a continuation of the supplypassage 3 of the cock, has communication with the interior of a tank 9or other suitable source ofliquid supply, in the present instance,through a tube or passage 10. A float 11 is mounted in the chamber 2 andhas a needle valve part 12 projecting therefrom and seating in a portionof the passage 10 to close communication between the chamher 2 and thesource of liquid su ply when the liquid is at a predetermined height insaid chamber.

I wish it understood that my invention is not limited to any specificform, construction or arrangement of the parts thereof except in so faras such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

1. A liquid feed means having a floatcontrolled feed and having multiplepassages therein, one passage being in lateral communication with asupply passage and being open to the atmosphere above and below itspoint of communication with said supply passage.

2. A liquid feed means having a supply passage a portion of which isenlarged, and having a drip-passage in communication with said supplypassage, said drip-passage being open to the atmosphere above and be lowits point of communication with the supply passage, a float valve in theenlarged portion of said supply passage to control the feed of liquidthereto, and a valve for controlling the communication between saidpassages.

3. A liquid feed means having a supply passage and drip-passage, saiddrip-passage being in communication intermediate its ends with thesupply passage and having its ends open to the atmosphere, aneedle-valve controlling the communication between said passages, and afloat-valve controlling the liquid feed through said supply passage.

4. A drip-cock having a passage in floatvalve controlled communicationwith a source of liquid supply and a drip-passage open at opposite endsto the atmosphere and in valve controlled communication with said firstpassage.

In testimony whereof, I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
